Abstract (en)
[origin: EP2408030A2] A light emitting device may be provided that includes a conductive support member (110), a first conductive layer (120), a second conductive layer (130), an insulation layer (170) between the first conductive layer and the second conductive layer, and a light emitting structure that includes a second semiconductor layer (150) on the second conductive layer, a first semiconductor layer (140), and an active layer (160) between the first semiconductor layer and the second semiconductor layer. The first conductive layer includes at least one conductive via (120a) that passes through the second conductive layer, the second semiconductor layer and the active layer. A top surface of the at least one conductive via is provided into the first semiconductor layer. The insulation layer (170) may substantially surround a side wall of the conductive via. The first surface of the first semiconductor layer may include a first surface area, a second surface area and a recess having a bottom surface. The recess is aligned with the bottom surface of the first conductive layer, and the first surface of the first conductive layer is aligned with the first area of the first surface of the first semiconductor layer. The first surface of the first semiconductor layer and the recess may have a surface roughness.
